Known as the Mk 11 Mod 0 to the US Navy and Marines, and the M-110 to the US Army, this rifle is a heavily-modified SR-25 battle rifle (q.v.). After extensive use in Afghanistan and Iraq by US Navy SEALs, the SR-25 was modified by Knight Armament Corporation (who had inherited the design of the SR-25), and it became the Mark 11 Mod 0 Rifle; it was later adopted by the US Army.

The Mk 11/M-110 is an enhanced version of the SR-25, and is designed for the spotter of a sniper team. Modifications include a new firing pin, ejector, extractor, and extractor spring, all to enhance reliability. The feed ramp is also improved, the gas ring is one-piece, and the bolt and barrel extension are redesigned. The magazines have been improved to allow a full 20 rounds of ammunition; previous AR-10-type magazines would sometimes fail to feed when more than 18 rounds were loaded into them. Both are equipped with a custom version of the Leupold Tactical Long Range T3.5-10x scope. In addition to the MIL-STD-1913 rail atop the weapon, there are three others on the handguards. A Harris S-type bipod is mounted under the front handguard. The flash suppressor was removed, replaced by a target crown. An adapter allows the Mk 11/M-110 to accept a special KAC silencer that is rated for 10,000 rounds of standard ammunition. The 20-inch barrel is free-floating, heavy, and match-quality, and the handguards have been modified to allow much easier removal and attachment.

That said, the Mk 11 Mod 0 and the M-110 differ in some details. The top MIL-STD-1913 rail of the M-110 is one continuous piece which is removable, while that of the MK 11 Mod 0 is two pieces, part of which is integral with the top handguard. The Mk 11 Mod 0 has a non-adjustable match-quality trigger unit, while the M-110 uses a two-stage match trigger unit. The Mk 11 Mod 0 uses standard fire selector controls, while those of the M-110 are ambidextrous. The Mk 11 Mod 0 does not have an adjustable stock of any sort (it uses an M-16A2 stock), while the M-110 uses an adjustable buttplate on a modified M-16A1 stock. (The Army also wanted an adjustable cheekpiece at first, but later deemed it unnecessary.) Both versions are brownish-tan in color, but the M-110 is darker than the Mk 11 Mod 0.

KAC has recently introduced a shorter version of the SR-25/M-110 called the SR-25 Carbine. This was reportedly developed at the behest of US special operations. It has for the most part the same features as the M-110, but has a sliding stock, and the barrel is a 16-inch floating heavy match-quality barrel tipped with a flash suppressor.
